About

Until

Pressing pause on biological time, for those who need it most.

We are building reversible cryopreservation technology to solve the organ procurement and matching problem. Cryopreservation is already essential to modern medicine — powering IVF and life-saving stem cell therapies. Now, we’re extending this technology to whole human organs — transforming hours of viability into weeks, or months, however long is necessary — so that no donated organ is lost to logistics, and no patient dies waiting. By solving this immediate need, we de-risk and build the foundation for what comes next: whole-body reversible cryopreservation. We're pausing molecular motion to give patients a bridge to future cures.
